TO ALL PERSONS TO WHOM THESE-PRESENTS MAY COME:4

Be it known that I, ELWIN E. BERRY, of Farmington', in lthe county of Straii'ord, and State of New Hampshire, have invented an Improved Table-Leni` Supporter; and I do hereby declare the same to be fully described in the following specification, and represented in the accompanying drawings, of which- Figure 1 is a front elevation, and

Figure 25a transverse section of aftable provided with my invention, Vwhich is an improved means or mechanism Afor supporting a leaf of the table when such leaf is in a horizontal position, such'mechanism -readily admitting of the table-leaf being dropped or turned on its hinges into a vertical position or plane.

In the drawings, A denotes a common table, having two leaves, a a, so hinged to opposite edges of its top, j

b, as to render each leaf capable of being turned from a horizontal down into a vertical position, or from the latter to' the former, as circumstances may require.

The .hinges of one of the leaves, or that which is represented inthe drawings `as elevated into a horizontal position, are shown at c e.\

In-carrying out my invention, I hinge or connectto the leaf a curved arm or strut, B, and extend itthrough a staple or yoke, c, xed to the lower edge of the next. adjacent bar, d, of the leg-frame ofthe table, such staple or yoke being formed as represented in the drawings.

The arm or 4strut B is chambered lengthwise to receive a gravitating-lever or catch, D, formed as shown in I `tige. 1 and 2. This latch turns on a pin, a, going through it and the arm or strut, and being arranged therein in manner as represented in fig. 2. l p.

When in its lowest position ther lever-catch D projects below the strut a short distance, and is supported by resting against the end of the chamber in` the strut. i

On elevating the table-leal' to a horizontal position, the gravitating-catch l) will drop downand, by bear ing against the front edge of the yoke or staple C, will, in conjunction with the curved arm, support the leaf in such position. p When the catch D is in its lowest position, its shorter arn1,j', will extend above the upper edge of the arm B, so as to enable a person, by grasping the arm and the part so extended, to readily move the catch, so as toY `threw it ont of engagement with the staple or yoke before proceeding to depress the table-leaf.

The advantage of the curved arm or strut and gravitating-catch over a curved arm only having one or more notches or `teeth to act against the yoke, is, that such an arm as lastmentioncd is vcr'y liable to be accidentally thrown out of engagement with the staple, particularly after the two may have become more or less worn. This may be occasioned by a person while leaning against the table-leaf, or while'sitting at the table.

With my invention, or combination of gravitating-arin nr catch with` the curved arm, the danger of acei-` dental disengagement of the table-lent` supporter with the staple or yoke is very much lessened, if not rendered impossible. l y

I would remark that, if desirable, a spring may be applied to the curved arm ,and its catch, so as to press the latter downward within the arm. i i f' What, therefore, Iclaim as myiinvention, is-

The combination of the lever-catch D,Vor its mechanical equivalent, with the arm or strut B, andthe staple- C,'so as to operate therewith, as described, when they are applied to a table or other like article, substantiallyV in manner as specified.
